Title: Beating-up motion for looms
IPC: D03D49/68
Filed: 1925-07-23
Abstract: 249,388. Kenyon, D., and Evans, H. July 23, 1925. Beat-up motions. - In a loose-reed loom, the reed is locked to make the beat-up by adjustable wedge-pieces 11 on a slide-rod 9 engaging between the inclined ends of reed-case levers 2 and wedges 6 on an anchorbar 5. Additional security is given by tapered locking-pieces 18, 20 on the reed-case spindle 3 and the anchor-bar 9 respectively. The rod 9 is spring-pressed against an adjustable cam-bar 28 on the loom frame so that it is moved to the left during the insertion of the weft to free the reed. If the shuttle encounters an obstruction, the reed is thrown over as shown in Fig. 10 to allow the shuttle to pass and the reed is then swung back without stopping the loom by a handlever on the rod 3. The stop 18 may be forked to embrace the stop 20. The engaging faces on the levers, wedges, and stops are inclined at an angle of from 5 to 20‹.

Title: Improvements in or relating to the manufacture of electrical coils
IPC: H01J29/76
Filed: 1946-06-22
Abstract: 633,625. Making electric components. BULL, E. W., and HOLMAN, H. E. June 22, 1946, No. 18802. [Class 83 (ii)] [Also in Groups XXXV, XXXVI and XL (a)] A coil is made by embedding or otherwise securing one or more conductors arranged to provide one or more convolutions in an insulating support which is then bent to arcuate or cylindrical form, the effective parts of the conductors preferably being parallel to the axis of the arc or cylinder. As shown, grooves are made in an insulating sheet 1 by engraving, moulding or pressing and are filled with metal, e.g. by electro-plating to form turns 2, the sheet then being bent into cylindrical form and applied to the neck of a cathode-ray tube. Alternatively, a sheet of conducting foil may be applied to the sheet 1 and the superfluous metal etched away by acid. As an alternative, wire could be bent to the configuration shown and then secured by adhesive to the sheet 1, or the turns could be disposed about pins disposed on a metal former to which sheet insulation, e.g. polystyrene, could then be applied to embed the turns. In yet another form, a pattern of the desired coil turns is printed in conducting material on a support of ceramic material which is then fixed to fuse the conducting material. Specifications 233,050, [Class 36], and 449,533, [Group XXXV], are referred to.

Title: Improvements in and relating to methods of making resinous materials
IPC: C08L61/22
Filed: 1930-06-20
Abstract: Synthetic resins are prepared by precipitating an aromatic amine-aldehyde condensation product in the presence of a suitable pulp during beating, at an elevated temperature, whereby large particles of resin are produced which adhere to the fibres of the pulp.  If the resin is required as an insulator, the precipitation is carried out at a lower temperature, the product washed to remove electrolytes, and the particle size then built up by heating.  The temperatures employed are from 40-100 DEG  C., the best results being obtained at 50-60 DEG  C.  The process is also applicable to the manufacture of moulding mixtures using fillers such as wood flour or asbestos.  Specification 352,140 is referred to.ALSO:Containing artificial resins and fibres.-An aromatic amine-aldehyde condensation product is precipitated in the presence of a suitable pulp during beating, at an elevated temperature, whereby large particles of resin are produced which adhere to the fibres.

Filed: 1956-06-22
Abstract: A metallic article is provided with a diffusion alloy coating by being heated in the presence of halide and the coating-metal, the latter being in the form of one or more sintered elements. The halide may be a liquid such as hydrofluoric acid with which the sintered elements are impregnated, or a powdered solid, or a gas such as fluorine which is introduced into the midst or vicinity of the sintered elements.  The sintered elements may consist of a number of balls which surround the article to be coated, or may be shaped to follow the contour of the article. Alternatively, for the coating of small articles such as iron or steel pinions or screws, a single sintered casing may be provided with cells each to receive a single article.  When coating long articles such as tubes and sheets, a continuous method is employed in that the articles pass through the furnace one after the other, the sintered elements either accompanying the articles or forming, for example, a tunnel or core along which the articles pass.
